' oLU'roHsACTUArINe DEVICE..

.To aZZ wir om Iz'z may concern: y Be 1t known that I, BENGT M. W. HANsoN,

a citizen of the United States, residing at Hartford, .in the county of Hart-ford and` State of Connecticut, have invented certain new and useful improvements in 'Clutch-2 Act-uating Devices, of which the following is a specilication. d I

This invention relates to clutch actnatmg devices, the object of the invention being-to can be connected v1with a shaft.

In the drawings .accompanying and form ing part of the present specification there is shown one convenient form of embodiment of the `invention `which to enable those skilled *in theart to practise the same Will be. fully set forth lin the following description, the'novelty of the invention being covered in the claims succeeding said description. From this it Will be clear that the invention is not limited to the exact showing made by said drawings and description as departures in several respects maybe made therefrom Within the scope of the invention defined by said claims.

Referring to said drawings: Figure l is a side elevation of port-ion of a shaper equipped with clutch actuating device in volving 'the invention. F ig. 2 is a. vertical section on the line 2.-2 of Fig. 1 looking in thedirection of the arrow, `and, Fig. is a sectional detail view of part of the driving and adjusting mechanisms, this view showing also clutch means. i

Lilie characters refer to like'parts through-` out the severalfigures of the drawings.

A clutch actuating device embodying my invention may be used in various connecf` tions, for example and as illustrated, it ma7 be incorporated in a shaper. The Shaper shown comprises a base or bed as 5 and a column 6 rising therefrom, the bed 5 being shown equipped with a Work holder 7. The column 6 supports the slide 8, and .llthough the same is represented ascapable of reciprocation in a verticaldirection, this is not a matter of consequence.. The slide is furnished with the shaping tool 9. 'Mounted in specification of'tettersratent. Patented Jan, 13 1914, Applica/nim inea aune 13. i912. serial No. 703,563.

'column is a spur-gear 13 having pivoted. on

one side 'the block oi" shoe 14 tting the longitudinal slot 15 in the outer arm of the 6o lever 10.. Hence, it will be evident thatvas the' spur gear 13- isrotated the slide 8 through the intermediate parts, will be moved down and up on the column '6. In mesh vwith the spur gear 13 is a' inion 1G' '65 i rigid `with the hollow shaft 1T which latter as will hereinafter appear is adapted to' be operated either by povver or hand. The shaft 17 and the connections between thesame and the slide, 8 are not uncommon in 170 this art and form no specific part of the present invention, for which reasonfclie'yA need Vnot-Abe described further in detail; ajmatte'r of fact .any other suitable shaft and j connections between the same and the slide -7`5 8 or its equivalent,m ight be utilized for the purposes in View. f The shaft 17 is provided with asuitable 'driver such as the" stepped pulley '18"lolose thereon but adapted to beo'peratively con- SQ .nected thereto as by aclutch, when it is de.

sired. to rotate the latter bylpou'er. Said shaft 17 is supported by and projects outward beyond the sides of the column 6.' -A rod 19 extends entirely through said shaft 'and 85 Connected with one end of the rod is a lever or equivalent device hereinafter described, for operating the same, While associated Withv the opposite. end o'f said rod is a clutch.- by which the driver or pulley 18can-be Kcons-.lim nected to or disconnected from the shaftflf, Pinned or otherwise suitably connected-to said' shaft 17- is the block 2() havino' af groove or channel 2 1 to receive the slidingV wedge which is adapted to enter between and spread, the companion levers 23 fitted between the ends of the split expansible ring :2sL fitted in the annular flange 25 projectingfoutward' from the pulley 18. The

'wedge 22 is pinned to the sleeve 2G by a 100 screw as 27, the sleeve in turn being pinned to one end ofthe longitudinally movable rod 19 as'by the pin 28. Consequently'it will be understood that when the rod 19 is-nioved longitudinally' of the shaft 17, the sleeve 26.

and-hence 'the wedge '27 .will be moved lin a corresponding direction. VVhe-n the-.rod 19 is moved to the right in Fig. 2 the wedge 22 will spread thelevers E23 so as to expand the*- di'vided, spring clutching ring 24 into frictional engagement With the flange to thereby clutch the pulley 18 to the shaftl 17 so 'thatzif said pulley be rotating the shaft will bedrivem On the movementof the rod 19 to the `left the ulley will be unclutched from the shaft. T e twol levers 23 are pivotedl to av longitudinally shiftable support 23 guided in a channelof .theblock 20.

" The clutch described is familiar in the mechanical arts so that a more detailed descriptionfofthe sameis unnecessary; some other typeffof clutch might be substituted therefor.

Itshould-also be stated that-the sleeve 26 is closed at theouter end, its inner portion "'o'verlyingthe lfiange 25 -so that the clutch parts Vare incased, and thereby protected.

- Supported by the shaft 17 and directly by its ends .fitting a 'peripheral groove in theisfactorily thisconne'ction. It Will be asa bushing 29 "thereon, is the slidable sleeve 30 connected. as by the pin 31 with the rod 19, so that when-the sleeve 30 is movedlongitudinally ofthe shaft 17th'e rod .19 will bel similarly operated and for thus/operating said sleeve the lever' 32ma-y be provided, said lever being pivotally'connected at its upper'end tothe bearing or bracket 33' on the'eolumn. 6 and having a stud 34:' betvv'een sleeve l30.

AKeyed Orl-otherwise' suitably fastened to theL shaft'l'Z '-isy afmanual operating member therefor', and the hand yWheel 35 answers -satsumed that thepulley; 18 isclutched to the shaft" 17 by' the clutch mechani -already described." In this eventthe-slide 8- through its described connections with said shaftI is f'j'rec'iprocat'ed'on the'rotatlon of thelatterx It will be assumed that itbe'comes 4necessary to adjustthe'slide4 8 to bring the tool 9 into a ldefinite relation with the work on the work support 7. "In this event theffollowing pro. cedure' maybe adopted:""f1`heV handle of the lev'er '32 will -be grasped and said lever thrustinward which moves' the 'rod 1? to theleft and therefore through 'the described parts, tends to' move they wedge 22 from between the tails'offthe'levers 23 to permit the contraction of the spring" ring 524, and the Vconsequent unclutching of `the pulley 18 from the shaft 17. When this occurs said shaft'rcan be vturned by hand through `the agency of the Wheel 35' toither raise 'or lower through the -intermediate described connections, the slide 8 and correspondingly adjust the tool 9; When the adjustment is obtained' the pulley 18 will be clutched to its shaft by the opposite operation of the lever 32 tol effect the operationof the vslide 8 by power.

That is claimed is:

, f1. The combination of a shaft, 4a rod extending entirely through the shaft, means for manually rotating said shaft, manuallyoperable means for reciprocating said rod,
